I recently installed a gtx960 2GB into my PC, when i tried playing some games i noticed it is not performing how it should. i know the 960 is no powerhouse but it should still be able to run grand theft auto 5 on the lowest settings with vsync turned completely off. i was getting 20fps avg in the prologue. i also experienced this on ark: survival evolved and battlefield 4. after researching, i think i am being bottlenecked by my CPU. sorry if im not much help, but im new to PC gaming and not overly experienced. here is my cpu:
AMD A8-7650K Radeon R7, 10 Compute Cores 4C+6G
